Renting vs buying is a question most of us never really ask. We need a drill, we buy a drill. We plan one kayak trip, we buy a kayak. Then the object spends the next five years in a cupboard while its value quietly melts away. The maths of ownership only works when you actually use what you own — and for a surprising number of things, we don’t.
This guide gives you a simple rule of thumb to decide when renting beats buying, with real numbers, so you stop paying full price for ten minutes of use.
The real cost of owning something you barely use
A mid-range cordless drill costs around €120. Studies on household tools famously estimate that the average drill is used for only 6 to 15 minutes in its entire lifetime. That works out to roughly €10–€20 per minute of actual use. A €700 camera used twice a year, a €400 kayak used one weekend each summer, a €500 games console that gathers dust after a month — the pattern is everywhere.
Ownership also has hidden costs people forget in the renting vs buying calculation:
- Depreciation: most consumer electronics lose 30–50% of their value in the first two years, whether you use them or not.
- Storage: in a city flat, every cubic metre you fill with idle gear is space you’re paying rent or a mortgage on.
- Maintenance: batteries age, seals dry out, software support ends.
Renting vs buying: the 10-day rule
Here is the shortcut we recommend. Estimate honestly how many days per year you’ll use the item, then compare:
| Item | Purchase price | Typical rental/day | Renting wins if you use it… |
|---|---|---|---|
| Power drill | €120 | €8 | fewer than ~15 days/year |
| Mirrorless camera | €700 | €12 | fewer than ~55 days/year |
| Kayak | €400 | €15 | fewer than ~25 days/year |
| Games console | €500 | €10 | fewer than ~50 days/year |
| Party tent | €300 | €25 | fewer than ~12 days/year |
In practice, if you’ll use something fewer than 10–15 days a year, renting is almost always cheaper once you factor in depreciation and storage. Above that, buying starts to make sense — and at that point you can even flip the equation and rent out your stuff to other people on the days you don’t use it.
When buying is still the right call
Renting isn’t a religion. Buy the thing when:
- You use it weekly (a commuter bike, your everyday laptop).
- It’s deeply personal — fit and hygiene matter (climbing shoes, helmets you’d rather not share).
- Availability is critical and you can’t risk it being booked (professional work equipment).
The third option: own it, and make it pay
The renting vs buying debate usually assumes ownership is a pure cost. It doesn’t have to be. Peer-to-peer platforms — part of the wider sharing economy — let you turn the idle days of things you already own into income. A camera that sits in a drawer 350 days a year can earn money on 20 of them and effectively pay for itself. We’ve broken down the numbers in our guide to how much you can earn renting out your stuff.

FAQ
Is renting always cheaper than buying?
No. Renting wins for things you use occasionally; buying wins for things you use constantly. The 10-day threshold above is a good first filter.
What about damage when I rent someone else’s item?
On Sharepact every rental is covered by damage insurance and every renter passes ID verification, so both sides are protected from pickup to return.
Can I do both?
Absolutely — many Sharepact users rent the things they rarely need and list the things they rarely use. It’s the same marketplace, working in both directions on Sharepact.
